PUMP.

I SPECIPIQATION forming part of Letters Patent No. 354,669. datedDecember 21, 1886.

' Application filed April 22, 1884.

To all whom it may concern:

Be it 1; nown that I, BENJAMIN O. VANDUZEN, a resident of Winton Place,in the county of Hamilton and State of Ohio, have invented certainnewand useful Improvements in Pumps, of which the following is aspecification.

The several features of my invention, and the various advantagesresulting from their use conjointly or otherwise, will be apparent fromthe following description and claims.

For the purpose of illustration I will now proceed to describe theseveral features of my invention as applied to one of the manydescriptions of pumps to which the features of my invention areapplicable.

In the accompanying drawings, Figure 1 represents a vertical centralsection of one form of double-acting force-pump, the actuating-lever,actuating-rod, pumpstock, and the upper portion of the discharge-pipebeing shown in elevation. Fig. 2 represents a plan view of the basewhich sustains the pump at the platform. Fig. 3 represents an edgeelevation of the brace-arch and extension for receiving the packinginterposed between the arch and suction-cylinder, and looking from leftto right toward that edge of the arch which is on the left hand inFig. 1. Fig. 4 represents an enlarged vertical central section of thevalve-seat of suction-cylinder, and Fig. 5 represents an enlarged topview of said seat. Fig. 6 represents a top View enlarged of the valveproper of the suction-cylinder.

A indicates a pump-stock of any suitable form.

B indicates the actuating-rod, operated by suitable means, preferably bya lever, C, piv-' otally fulcrumed to the head or top of the pump-stock.

To the stock A is connected the dischargepipe D, passing'up into thestock and com municating directly, or by means of a conduit in thepump-stock,with a discharge-orifice, E, of any suitable configuration.

The pump-stock and discharge-pipe D, and whatever of the lower portionsof the pump is suspended and upheld by the pipe D, are all supported bythe base F, provided with an opening, G, for the admission of thedischargepipe D.

Where the cylinder or cylinders of the Serial No. 128,889. (No model.)

' side of the opening G, and in base F, is a recess, a, formed for thereception of a key, R, adapted,when the discharge-pipe G is in place,to'be driven into said recess a, and hold the discharge-pipe rigidly inplace in the base F. To the lower or bottom portion of thedischarge-pipe is secured, preferably by a screwthread, as shown, asuction-cylinder, M. In the present instance a dischargebranch, M, ofthe cylinder is screwed over and onto the pipe D. In this cylinder M isthe suctionpiston K, having preferably a packing so placed as to allowthe piston to be easily insertedinto or withdrawn from the cylinder Mwithout disturbing said packing.

In the present instance the packing r is turned upward at its outeredge. A suitable valve is connected to or combined with this piston, thepreferable form of such valve being a discal valve, as shown. The pistonK is preferably connected to the actuating rod either directly as in asingleacting pump or by an intervening connection as aforoing-piston,or, as in the present instance, a hollow plunger, J.

I indicates a brace-arch, whose object and -functions will be fullyhereinafter set forth. The plunger J reciprocates within said arch.

The upper end of this plunger J is preferably connected directly, asshown, to the actuatingrod, and the lower end is centrally provided withan extension or rigid connection, I), connecting this plunger J to thesuction-piston K. At the side of this connection I), and in the lowerend of the plunger J, is one or more openings, d. These openings serveto make communication between the space within plungerJ and the interiorspace of cylinder M, and in this way enable plunger'J to operate 'as anair-vessel in connection with the discharge-conduit D.

The brace-arch I is preferably upheld and supported and connected tocylinder M as follows: It is provided near its lower portion with anoutwardly extending annular flange, e. Be-

low this flange it is provided with a downwardlyextending annularextension, S, and this extension S is provided with an annular bead, T,the latter being so located as that a space is left between the flange eand the bead T. Upon this extension is slipped or placed a rubber orother elastic packing, L, of a peculiar shape-that is to say, thepacking is auannular-shaped body adapted to fit againstand closelyembrace extension S, and consequently it has interiorly an annularrecess, T, which receives and closely embraces the beadT of theextension S. This packing is provided at.

its upper end or portion with a horizontallyextending annular flange, f,of the diameter of the adjacent bearings of the annular flange e ofbrace-arch I and cylinder M. The packing has also a ledge or straightvertical portion, g, which fits closely within the cylinder M, and theflange f rests upon the bearingsurface h of cylinder M, and between itand the bearinging-surfacej flare e of the brace-arch. The lower end ofthis packing L is provided with a flange, X, extending inwardly andclosely embracing the lower end of extension S of the brace-arch I andextending inwardly against the periphery of plunger J. Thus the packingL serves the double function of being a packing between themeeting'surfaces of the cylinder M and brace-arch I, and also of being apacking for preventing fluid in cylinder M from passing betweenbrace-arch I and plunger J. The annular ledge g operates as a guide toguide the packing L and brace-arch into proper position in cylinder Thebead T of extension S, in connection with recess T in the packing,serves to prevent the packing from slipping off of or from the extensionS. Obviously the bead T might be formed on the inner side of the packingand the recess T be formed on the outer side of the extension andaccomplish the same purpose. Such change or reversal is included in myinvention.

Brace-arch I is kept securely against the packing L and the packing Lsecurely against the cylinder M by any suitable means, preferably by thefollowing means: The lower end of tube V enters and sits in a recess orcavity in the upper end of brace-arch I. The upper end of said tube Vsits in a recess or recessed extension, k, of the cover Q. The cover Qis suitably secured to place upon the base, an approved and ordinarymeans being the bolts 2 l, passing through lugs on the cover and screwedor bolted to the base. When the bolts Z Z are thus screwed down, thecover will press down upon tube V and brace-arch I will be held firmlydown upon the packing L and will compress this packing against cylinderM, and thus the brace-arch I will be held down to place by means of thispressure, and the packing L prevents any lateral movement of the saidarch I; and the joint between plunger J and cylinder M will be fluidtight.

In the bottom of the suction-cylinder are the Z closes.

' suction-valve, valve-support, and seat of any desired form, butpreferably of the following useful construction: The suctionclapper-valve Zpreferably consists of, as usual, an annular portion ofleather or any pliable substance,

and this valve-is preferably surmounted by a weight, m, connected to thevalve 1 by a central screw, m. This valve Z rests upon an annular diskor plate, N, of rubber or other elastic material, (preferably ofrubber.) The disk is preferably flat on the bottom and formed at the topinto a raised or sandseat, t, surrounded by an annular sand-groove, V.This valve-seat N is'provided with a central aperture, m, passingvertically through the seat and within the annular sand-seat. Thediameter of this annular disk N and the diameter of the valve 1 arepreferably the same, and the diameter of each is enough to extend underthe bearings of cylinder M and form the joints. The disk N rests upon asuitable plate or cap, as P. This plate P is suitably secured to thecylinder, preferably by bolts, as 10, located at suitable intervalsaround the cylinder M. These bolts being tightened,

the valve 1 and the disk N are tightly com-.

pressed between the plate P and the end of the cylinder M, and are thusheld firmly in place and the joints between said parts are renderedfluidtight. The plate I? is provided with a central aperture, P.

The advantage of the sandseat made of an elastic substance is that theseat repels the sand that would, if the seat were a non-elasticsubstance, bed itself into said seat. Thus the valve-seat is kept freefrom sand and is preserved for a long time. The advantages of asand-seat made of rubber are that suchaseat not only repels the sand andkeeps itself free from sand, but also prevents the leather of the valvefrom corroding or hardening, as the latter does when it comes intocontact with a metal seat.

The mode in which the pump I have now described operates is asfollows:The piston K being lifted, the water is drawn up through valve Z intosuction-cylinder M, and the valve 7 The piston K being depressed, the 7water in cylinder M passes through piston K,

and the plunger J coming down presses a part of this water up into thedischarge-conduit. The air in plunger J, compressed as piston K rose,now expands and conduces to render the flow through thedischarge-conduit even and regular. As the piston K rises it draws up afresh supply of water from the well, and also lifts up the water aboveit and forces into the discharge'conduit a portion'of the said waterwhich is above it and in said cylinder M. The air in plunger J,compressed as plunger descends, now expands and conduces to render theflow of water from the discharge even and regular. Obviously, thatfeature of my invention which consists in a base having an opening, G,combined with the discharge-conduit D and a key, B, may be applied toany pump carrying a discharge-conduit. Obviously,also,

IIO

that feature of my invention which relates to the rubber seat made ofelastic substance, &c., is applicable to other pumps and to checkvalves,foot-valves, 85c.

While the various features of my invention are preferablyemployed-together, one or more of said features may be employed withoutthe remainder, and one or more of said features, in so far asapplicable, may be applied to pumps of descriptions other than thatherein specifically described.

What I claim as new, and desire to secure by Letters Patent, is

1. The combination of brace-arch I, having ing against the plunger J,and piston K, rod

B, tube V, cover Q, and base F, substantially as and for the purposesspecified.

3. The combination of cylinder M, plunger J, brace-arch'I, extension Sand its bead T, and packing L, having recess T and'straight portion orshoulder g on said packing, and flange X,overlapping the lower edge ofextension S and pressing against plunger J and piston K, rod B, andmeans for holding the bracearch I, packing L, and cylinder M firmlytogether, substantially as and. for the purposes specified.

4. The combination of cylinder M, plunger J, brace-arch I, extension Sand its bead T, and packing L, having recess T and flange X, attached tothe said packing and overlapping the lower edge of extension S andpressing against plunger J and piston K, rod B, tube V, cover Q, base F,discharge-conduit D, stock A, and key R, substantially as and for thepurposes specified.
